Overview
All Cycles 20 to 25, as well as all of those with numbers 200 or higher,
always use identical cycle parameters, such as the set-up clearance
Q200,
which you must enter for each cycle definition. The GLOBAL DEF
function gives you the possibility of defining these cycle parameters
once at the beginning of the program, so that they are effective
globally for all fixed cycles used in the program. In the respective fixed
cycle you then simply link to the value defined at the beginning of the
program.
The following GLOBAL DEF functions are available:

Use the INSERT SMART UNIT function (see Special
Functions chapter in the Conversational Programming
User's Manual) and then UNIT 700 to insert all GLOBAL
DEF functions into a block.
